Best method/ tools for measuring bullets?

[AusFclass]

Hi all!

I guess there is a couple of parts to this question.

First what part of the bullet should be prioritized when measuring long range VLD or hybrid type bullets? Obviously longer bearing surfaces can create more friction but variations in ogive and boat tail can cause drag variations so what do you believe should be first point of call and to what tolerance to you feel is acceptable?

Secondly I have used either 1 or 2 bullet comparators installed on a set of verniers but due to the shallow angles on the bullets where the standard comparators bare any slight change is pressure or angle that the bullet is inserted at causes a large variation in measurement. I think I'm reasonably good with measuring tools (part if my trade) but I struggle to get a consistent reading on the same bullet over and over. I wonder how many people measure 1 bullet once and take that gospel.

I generally sort several hundred bullets at a time so I'm wondering what you guys and maybe some.of the bullet makers uses to measure bullets, and various SECTIONS of the bullet, with reliable accuracy and at a reasonable pace.

Thanks in advance! Any help would be greatly appreciated

Can sell you a metal ruler mate... postage from WA might be a killer tho! I just use a hornady comparitor on one end of the verniers and a sinclair nut on the other. Ogive goes into the nut, boat tail into the hornady comparator. I dont batch by 1 thou increments so there is a little room for operator error...

Yeah I recon the ruler might be the go!! I hear those ones from cheap as chips are the best? Something about the paint they uses having a lead composition closest to the bullet core??

I made my own comparator from a section of barrel using the same reamer to cut the chamber of rifle used. Doesn't get much better than that!

Here is what I do. Still working through testing to see if it's worth it. So far it is.

Sort using Mark King Rifles bearing surface measurement tool and place into seperate piles. Then use Bob Green's bullet sorting tool. Next use Montour County's meplate trimmer and lastly pont using Whidden's die pointer.

Good Shooting
